It’s a Glen McKenna 35, the favourite of Barney Stinson, the character played by Neil Patrick Harris in How I Met Your Mother.

It’s all a little surreal, because we are on the Los Angeles set of MacLaren’s Pub, the fictional bar that the gang hangs out at. Also, there’s no such thing as Glen McKenna 35.

The Canadian is drinking Macallan 12, which has been poured into bottles with a different label.

“What can I get you, sir?” asks Smulders. She doesn’t arch an eyebrow when the reporter orders a Coke, congratulating himself for resisting the impulse to make it a diet version.

Smulders, 31, was filming the last few episodes of the hit series, which ends March 31 at 8 p.m. on City TV and CBS.

“Some days I’m totally fine, but then I realize it’s going to be the last time and I get really nostalgic and sad,” says Smulders. “But I have so much overwhelming gratitude to the show, it’s been the best job. It’s hard to get mad or sad when you’ve been given such opportunity.”

The show, one of TV’s most successful sitcoms of the past decade, premiered on CBS in 2005. It details the lives of an eclectic group of friends based in Manhattan, including Smulders’ character, television reporter Robin Scherbatsky.

The series revolves around Ted Mosby (played by Josh Radnor) narrating to his children through a series of flashbacks about how he met their mother.

Smulders said she cornered co-creator Craig Thomas earlier in the year to get the lowdown on what was planned for the ending.

“I asked him what was going on and, when he told me, I totally lost it; I started crying. I’m excited for fans to finally see it,” said Smulders, who was born in Vancouver, B.C.

There has been lots of speculation on how it will end, including one theory that has the mother (Cristin Milioti) dying in the end. But the actress told the Hollywood Reporter recently that it was just an “insane conspiracy theory.”

Smulders describes the ending as “beautiful” and said that fans won’t be disappointed.

The show long had a soft spot for Canadian fans and did an entire show lampooning Canada with guest stars such as Alex Trebek, k.d. lang, Geddy Lee and Jason Priestley. But Smulders says Canadiana won’t be a big part of the finale, although she’s not ruling anything out.

“You mean that Canadian episode wasn’t enough for you? Although you never know, there’s always an opportunity for something to happen.”

So far Smulders has not put dibs on any props. The one thing she would have liked is already taken: the leather jacket that belonged to her alter ego Robin Sparkles when she was a teenage pop star in Canada with hits like “Let’s Go To The Mall.”

“It’s already been claimed for a pile of things that go into posterity for I’m not sure what,” says Smulders.

Maybe one day it will hang next to to the Fonzie jacket in the Smithsonian. You never know.

For now, the hardest thing for Smulders is saying goodbye to the crew.

“I will likely see more of the cast and this will be the hardest thing of all to say goodbye to the crew rather than objects to steal at the moment.”

Fans won’t miss Smulders for long after the show wraps. She also appears in Captain America: The Winter Soldier, in theatres April 4. And you can see her next year in her recurring role as S.H.I.E.L.D. agent Maria Hill in Avengers: Age of Ultron.

She is also be giving up Los Angeles and moving to New York City, where she says she will pursue theatre as well as film.

“It’s an exciting new chapter, but I’m so grateful that this was a part of my life and my family for so many years.”
